他の構造をスイッチケース構造に変換する場合

Question

if else構造をスイッチケースに変更して、スイッチケースに変更する方法を変更したいと考えました。

<?php 
    header('Access-Control-Allow-Origin: *');//Should work in Cross Domaim  ajax Calling request 
mysql_connect("localhost","root",""); 
mysql_select_db("ocean"); 
if(isset($_GET['type'])) 
    { 
    $res = []; 


    if($_GET['type'] =="add"){ 
    $name = $_GET ['Name']; 
    $lname = $_GET['Lname']; 
    $userN = $_GET['User']; 
    $passW = $_GET['Pass']; 
    $gen = $_GET['Gender']; 
    $mail = $_GET ['Email']; 
    $mobile = $_GET ['Mobile']; 
    $address= $_GET['Address']; 

    $query1="select uid from oops where email='$mail'"; 
    $result1= mysql_query($query1); 
    if(mysql_num_rows($result1)>0){ 
     $res["flag"]= TRUE; 
     $rest["message"] = "There is already a user with that email!"; 
    }else{ 
    $query1 = "insert into oops(username, password, firstname, lastname, gender, email, mobile, address) values('$userN','$passW','$name','$lname','$gen','$mail','$mobile','$address')"; 
    $result1 = mysql_query($query1); 

    if($result1) 
    { 
     $res["flag"] = true; 
     $rest["message"] = "Data Inserted Successfully"; 
    } 
    else 
    { 
     $res["flag"] = false; 
     $rest["message"] = "Oppes Errors"; 
    } 
    } 

    } 
    if($_GET['type'] =="edit") { 
     $id=$_GET['id'];

     $res["flag"] = true; 
     $rest["message"] = "Data Updated Successfully"; 
    } 
    else

     $res["flag"] = false; 
     $rest["message"] = "Oppes Errors"; 
    } 
    } 
    if($_GET['type'] == "delete"){ 
     $id=$_GET['id']; 

     $query1=("DELETE FROM oops WHERE uid='$id'"); 
     $result1= mysql_query($query1); 
     if($result1){ 
      $res["flag"] = true; 
      $rest["message"] = "User deleted Successfully";

     } 
     else{ 
     $res["flag"] = false; 
     $rest["message"] = "Oppes Errors";

} 

else{

Answer 1

switch($_GET['type']) { 
    case "add": 
     //do something 
     break; 
    case "delete": 
     // do something else etc 

    default: 
     //if none of the cases apply, do something here (same as else in if-elseif-else) 
} 

Answer 2

switch($_GET['type']) { 
    case "add": insert code here; break; 
    case "edit": insert code here; break; 
    case "delete": insert code here; break; 
    default: insert code of last 'else' here; 
}

私はそれを行う方法がわからないとどのように私は同じページに変数にisset($_GET['type'])値の値を格納しますAlexander O'Maraはユーザーの入力を消毒し、最新の機能を使用しています。関数（「I」末尾せず）をmysql_はPHP 5.5.0以降廃止され、あなたが変数にタイプを格納し、例えば、その上にスイッチを使用することができる

Answer 3

PHP 7から除去されています

$type = $_GET['type']; 
switch($type){ 
    case "add": 
    .. 
    break; 
    case "edit": 
    .. 
    break; 
}
